Cisco limit bandwidth per VLAN for guest network

Hello guys,

Another question for you! I am trying to set a bandwidth limit on a certain VLAN in our network. This VLAN is used for our guest WiFi network. The goal is to make sure this VLAN has a maximum throughput of 2 Mbps download and 2 Mbps upload.

We currently have a Cisco Router 2911 and a Cisco ASA 5510 firewall.

I am not exactly sure what the commands are to make this happen. If you need more info on our current config, let me know.

Thank you!

1:

Apply rate-limit


2:

Policy a specific VLAN number on VLAN interface.

class-map vlan1
match vlan 1
match class-map class-default

policy-map vlan1-limit
class vlan1
police 50000000 250000 exceed-action drop

int vlan1
service-policy input vlan1-limit


the traffic with VLAN 1 coming from any will be shaped at 50Mbps

How do I apply the rate-limit? By doing your steps on part 2? Sorry not exactly a Cisco expert here ;-).

Also should I put in these commands on the router or the ASA?

Thanks!

It might be better to limit traffic from the WiFi network (I'm assuming its on its own IP range?)

Lets assume that your WiFi network is 10.0.0.0/24, and its coming in through interface 'wifi'.


access-list ip-qos extended permit ip 10.0.0.0 255.255.255.0 any

access-list ip-qos extended permit ip any 10.0.0.0 255.255.255.0

class-map qos

match access-list ip-qos

policy-map qos

class qos

police output 20000

police input 20000

service-policy qos interface wifi

This did the trick for us. A more effective way to make sure we can exclude the guest network from the internal network. Thank you!
